Most test patterns require full backlight as standard procedure. So it does cost a bit more battery when displaying patterns. And some special pattern (e.g.Noise pattern, requires to calculate real time random pixels) will cost more power than normal patterns. But if you exit pattern page, it will restore previous backlight settings. Thanks!

Display Manager can change display parameters of your android device. Yes! both Density and Resolution can now be changed on fly without even rooting your device (needs Root on 4.3 and above android versions). You can increase resolution to match the ever changing market of Android. Get view of tablets on phone, increase resolution to get more space on screen and increasing sharpness of screen in doing so. Decrease them to gain performance in games that scales well as expected making the tool a Battery Saver and Game Booster ...

* Display Manager can provide even better results when combined with our other apps such as Tegra Overclock or Exynos Overclock whichever suits your device*

What you can achieve with this?

* Boost gaming performance in GPU heavy games by lowering resolution without any CPU or GPU Overclock and fix lag in many situations.

* Custom Resolution and Density support for ease of use and flexibility.

* PPI and Resolution that are years to come. ( For example Samsung Galaxy S4 was able to achieve 3840*2160 resolution and 1764PPI !!! What you think its fake then see the last picture that has ANTUTU Benchmark detecting the resolutions changed and if you don't believe that too then why not test by yourself?)

* (Ignore this point if you are not a developer)For developers it packs a testing environment in which they can test both phone/tablet versions of app on same device. If you change only resolution then the phone falls under Large Value category and hence some apps that has Tablet interface will use dual fragment mode on phones! making the app act as a display scalar ...

* For people who loves to take benchmarks this app raise the phone ratings too if Resolution is lowered as this increases 3D/2D performance.

* Save yourself from purchasing another device just because you need a better and sharper display that costs as much as 800$ with the help of Display Manager !

About license issuesFor the first time it may say not licensed when purchased from play store, please close & open again in working internet.

What are side effectsThe app don't come without problems of course! Android is not adapted to Resolution change or being honest not all apps are adaptive. Some launchers, keyboards and other not well written apps will face issues. Games will have no problem as they are driven by engines that consider all device sizes. Also some device with capacitive buttons such as HTC ONEX will lose control of these buttons.

How to cope with these side effects?Best answer is finding an alternative app that does the same work. For launchers there are many free ones on play store (say Apex launcher, Go launcher etc.) For capacitive button problem there are apps such as Button Savior that can emulate virtual buttons for you that too is free!For keyboard you already know there are many free available already!

WARNING & DISCLAIMERAlthough this app don't require root to work but this does require your device to have ANDROID 4.2 versions. Anything higher requires Root!!!

********NOTE******We strictly discourage using pirated apps and or even cracked stuff. So if the app is used on a modded Google Play store that will not work! Use original stuff, pay a little for the efforts and you will enjoy the experience.

Full data encryption (AES strength)All data you enter will be encrypted before save! It is tough task to decrypt the data even your data is exposed by some reason.

Text NoteUser can save privacy note with this app, do not afraid of be watched by "CLOUD", swpie to mark it as finished or not, set diff importance level, sort note with diff ways, also can share to others...

ChecklistChecklist is a collection of note, can be easily used for check check item of same job (e.g. travel requirement). All check item is same function as text note.

Picture NotePick a picture from album or take photo from camera, the app will encrypt it and save. After that user can view/browse pictures inside the app without decrypt data to external file! Of course, user can send picture to others with share function. :)

Password BankNowadays, we have too many accounts/passwords to remember. Same passwords are dangerous, diff passwords are difficult to remember, so you can save them in security password bank (SPB)! It also suuport add multi account to same site easily.

This app is used to sync users' data from app "Droidsail Privacy Safebox" to selected web driver. User of "Droidsail Privacy Safebox" can backup data to web drive or restore app data from web drive. Or if user have more than one mobile devices, he can use this to sync app data for all his device with web drive.

Data is kept encrypted when transfer between device and web driver (So it is safe to backup your data on selected web drive as same as on your device). The speed of sync is depends on data size you have (e.g. pictures takes much more time to sync than text notes).

Now we support:1. Dropbox;2. GoogleDrive;3. Microsoft SkyDrive;

Functions:1. Sync data from local device to web driver:When first time launch the app, or user has deleted data on web drive, the app will prompt user to sync data from local to server.

2. Sync data from web drive to local device:When there is no dat in local device and valid data on web drive, the app will prompt user to sync data from server to local.(If user want to discard local data and get full backup data from web drive, he/she can launch "Privacy Safebox" and destroy data in "Settings->Data Options", and then launch "Data Sync" to get backup data.)

3. Bidirection sync:Normally, it will sync data between device and web drive in bidirection. New data on local device will be update to web drive and new data on web drive will be update to local device. This is very useful for user has multi device and want keep sync between them.

ATTENTION:1. If user has deleted data on web drive manually, and want sync fresh data on device to web drive again. Please DISCONNECT connection by selecting it in menu, since some web drive (e.g. Dropbox) required relogin web drive in such case.

(Since sync function requires more permission, so we implement it as single app, if user does not want to sync data, his/she can use only "Droidsail Privacy Safebox" for "clean"(no internet access) and slim, in KB size.)

1. Block permission (AppOps manager): Android (since v4.3) has provided a feature "AppOps" to limit app to access system functions (e.g. Notification, Camera, GPS, etc), but it is hidden API for now.

2. Block AutoStart (Autorun manager): Some apps can auto start in background without user's permission by using "receiver" mechanism of system. This function expose all receivers of each app to user, and user can config receiver status to disable app auto start on certain case;

The default brightness control (in system setting) is using backlight only. But in this app, it can filter your whole screen with a custom r/g/b color and blend level besides backlight control, which could get more useful effect(e.g. more red/green/blue/dark. etc) for different purpose (for night, reading, match wallpaper, user style, etc).

And this app is extremely easy to use, all control options are in one single float window. After first launch, a notification icon will appear on your top bar and you can adjust filter at any time. Also, this app provide a desktop widget to launch the filter control panel for convenience.

Your can set/clear "Start on boot" to ask the app to run/stop after device rebooted. And if you want the app to fully exit (including close filter and remove the notification icon), just check "Fully exit mode" and click the top-right exit button. It's easy, right? :)
